It consists of the next three aspects: firstly, we study Murthys' open problem whether the augmented matrix is a Q0-matrix for an arbitary square matrix A , provide an affirmable answer to this problem , obtain the augmented matrix of a sufficient matrix is a sufficient matrix and prove the Graves algorithm can be used to solve linear complementarity problem with bisymmetry Po-matrices; Secondly, we study Murthys' conjecture about positive semidefinite matrices and provide some sufficient conditions such that a matrix is a positive semidefinite matrix, we also study Pang's conjecture , obtain two conditions when R0-matrices and Q-matrices are equivelent and some properties about E0 ∩ Q-matrices; Lastly, we give a counterexample to prove Danao's conjecture that if A is a Po-matrix, A ∈ E' A ∈ P1* is false, point out some mistakes of Murthys in [20] , obtain when n = 2 or 3, A ∈ E' A ∈ P1*, i.e.
本文分为三个部分,主要研究了线性互补问题的几个相关的公开问题以及猜想:(1)研究了Murthy等在[2]中提出的公开问题,即对任意的矩阵A,其扩充矩阵是否为Q_0-矩阵,给出了肯定的回答,得到充分矩阵的扩充矩阵是充分矩阵,并讨论了Graves算法,证明了若A是双对称的P_0-矩阵时,LCP可由Graves算法给出;(2)研究了Murthy等在[6]中提出关于半正定矩阵的猜想,给出了半正定矩阵的一些充分条件,并研究了Pang~-猜想,得到了只R_0-矩阵与Q-矩阵的二个等价条件,以及E_0∩Q-矩阵的一些性质;(3)研究了Danao在[25]中提出的Danao猜想,即,若A为P_0-矩阵,则,我们给出了反例证明了此猜想当n≥4时不成立,指出了Murthy等在[20]中的一些错误,得到n=2,3时,即[25]中定理3.2中A∈P_0的条件可以去掉。

Huang and Lin proposed the weak solution concept for Backward Stochastic Differential Equation This paper based on the predecessor's work , gives the weak solution concept for Backward Stochastic Differential Equation with continuous martingale,uses the Girsanov transformation, obtains its weak solution of the existence of a necessary and sufficient conditions, and on this basis obtains its weak solution of the existence of sufficient conditions,these sufficient conditions weakened the drifting coefficient which requested in the existence uniqueness of strong solution to satisfy the Lipschitz condition the request.
本文在前人研究的基础上,给出由连续鞅驱动的倒向随机微分方程弱解的概念,利用Girsanov变换,得到其弱解存在的存在的一个充分必要条件,并在此基础上得到了其弱解存在的一些充分条件,这些充分条件减弱了在强解的存在唯一性中要求的漂移系数满足Lipschitz条件的要求。

However, the study indicated that the fecundation ability was decreased no matter what cryoprotective mediums and what freezing methods were used, companied with the losing of proteins, changing of proteins expressing quantity and increasing or decreasing of the function and activity in sperm after cryopreservation. Now, the study is altering to exploit the essence of the change of protein structure and function, and elucidate the cryodamage mechanism of sperm cryopreservation, which may provide the basic theory for cryopreservation of boar semen and promote the rapid development of the technique of boar semen cryopreservation.
但研究表明,无论采用何种冷冻保护剂、何种冷冻方法都损害了精子的受精能力,并伴随有蛋白质的丢失、表达量的改变、功能活性的增减等,这种研究现状迫使该领域的研究向充分揭示冷冻对精子损伤的机理方向转移,希望通过揭示冷冻保存所导致的蛋白质结构和功能改变的实质,充分阐明冷冻损伤的机理,为猪精液冷冻保存提供理论依据,并最终促进猪精液冷冻保存技术的快速发展。

However, methods and references for difference equation are relatively less. The new method proposed in this paper transfer the complex boundary value problem into the existence and uniqueness of the solution of the linear equations. For linear case , we obtained the necessary and sufficient conditions for the existence and uniqueness of the solution for the BVP; For the nonlinear case ,we got a series of new sufficient conditions by using contraction mapping theory and cone theory .
而差分方程边值问题的研究方法和文献还很少,文中新的研究差分方程边值问题的方法是将复杂的边值问题求解转化为代数理论中的线性方程组解的存在和存在唯一问题;对线性情形,较容易地获得了边值问题的解存在以及唯一的充分必要条件,而对非线性情形,则通过压缩原理和锥理论等各种不动点定理,获得了一系列新的充分条件。

In this part,chpater 2 is about how to overcome the problem of uncomplete information.
在这部分中,第二章研究信息不足的制度克服;第三章研究信息不对称的制度克服;第四章研究信息错误的制度克服;第五章主要研究制度如何降低信息成本,该内容有相当部分散见于第二、三、四章之中,之所以还要对其单列一章作专门的论述,是因为信息成本的降低是信息失灵问题是否得到克服的最为重要的指标,信息成本的充分降低表明决策主体的信息充分、准确且对称分布性,这有助于减少决策主体的支出,增加其决策利益,因此需要对信息成本降低的障碍及路径等问题展开研究;第六章研究公权信息的公开问题,该章主要对公权信息的强制性披露问题进行研究,它本质上是一种克服信息不对称的制度,所以把它列入第三章第一节第一部分有关强制性信息披露制度之中也并无不可,但由于公权信息的公开涉及到公权层面,与有关对私权主体的强制性信息披露制度相比具有较多的特殊性,所以,本文对其专列一章予以阐述。
